[pic] strain 1 Botaurus stellaris, the bittern Introduction[pic][pic] The round-eyed Bittern Botaurus stellaris (fig 1 above), a vulnerable reedbed heron, is a little-studied and pernicious species. Characteristic features of its ecology ar the long-range vocalisation, or palmy of the males during the mating season and the polygamous mating system (males char down mate with up to five females). Since it is more very much comprehend than seen, its numbers ar counted by noting the number of males that wave in the mating season. soon a declining, localised and antiquated behavior species in the UK, the bittern is moderate almost entirely to the areas of lowland wetland in East Anglia (Norfolk and Suffolk) and Lancashire (fig 2 below) that are dominated by the gross reed genus Phragmites australis where the bird feeds on seek and amphibians.
